Worth grading — even a PSA 9 beats raw

A Grade 9.5 Bob Grich #28 sells for $278 against $4.15 raw: a $274 spread, 67× the ungraded price. Even a PSA 9 ($252) clears the raw price after an economy-tier ~$25 fee, so a near-miss still comes out ahead. Centering is the usual reason a clean copy misses the 10 — measure it before you submit.
